Peridium, “an external coat or skin covering over the parts of reproduction, as in Lycoperdon [fungus]. Also a membranous, dry receptacle, usually containing a large quantity of powder” (Lindley); (in fungi) “the wall or limiting membrane of a sporangium or other fruit-body” (Ainsworth & Bisby); (in fungi) “the outer, enveloping coat of a sporangium or fruit body” (S&D): peridium,-ii (s.n.II), abl. sg. peridio, nom.& acc. pl. peridia [> Gk. peridion, dim. of pera, wallet + Gk. dim. -idion]; see gleba,-ae (s.f.I).
